TPS26600RHFR Overview
An eFuse (electronic fuse) is a semiconductor-based circuit protection device that replaces traditional fuses and hot-swap controllers. It integrates power MOSFETs, current sensing, and control logic to provide overcurrent, overvoltage, and reverse polarity protection. In the power management hierarchy, an eFuse falls under power management ICs, specifically within the category of hot-swap controllers and circuit protection devices. The TPS26600RHFR enhances system reliability by eliminating the need for external protection components and enabling precise, resettable protection.
Key features include integrated reverse input polarity protection down to -60V without additional components, adjustable current limit via an external resistor, and a full suite of protection features such as overvoltage, undervoltage, and thermal shutdown. The device also supports programmable startup delay and fault timer, enabling controlled inrush current during hot-swap events. Its wide input range makes it suitable for 12V, 24V, and 48V industrial buses.
Technically, the TPS26600RHFR uses a linear regulation scheme to limit current, with an internal charge pump driving the high-side MOSFET. The integrated back-to-back FETs provide reverse current blocking, preventing current flow from output to input during reverse polarity conditions. The device features a fault output (FLT) and enable input (EN) for system-level control, and its accuracy is maintained through a precision current-sense amplifier.
Typical applications include programmable logic controllers (PLCs), motor drives, battery protection, and power distribution in industrial automation. Its ability to handle up to 60V makes it ideal for 48V telecom and server power architectures. The device is also used in automotive body control modules and infotainment systems where reverse battery protection is critical.
When designing with the TPS26600RHFR, ensure proper PCB layout with adequate copper area for thermal dissipation, as the device can dissipate significant power during current limiting. Place the current-limit resistor close to the ILIM pin and use Kelvin connections for accurate sensing. The device's thermal shutdown protects against overtemperature, but thermal design should be verified for worst-case conditions.

Key Differentiators
- Integrated reverse polarity protection down to -60V (vs TPS26600PWP)
- Adjustable current limit from 0.1A to 2.23A (vs TPS26602RHFR)
- Compact VQFN-24 package (vs TPS26600PWP)
Design Notes
During current limiting, the TPS26600RHFR can dissipate significant power. For example, at 24V input and 2A limit, power dissipation can reach 48W. The VQFN-24 package has a thermal resistance of approximately 30°C/W, so ensure adequate copper area and thermal vias to keep junction temperature below 125°C. Use the exposed pad for heat sinking.
Place the current-limit resistor (RILIM) close to the ILIM pin and use Kelvin connections to avoid parasitic resistance. Input and output capacitors should be placed as close as possible to the IN and OUT pins. Use a 0.1µF ceramic capacitor on the EN pin for noise filtering. Follow the layout guidelines in the TI datasheet (SLVSD08) for optimal performance.
Do not exceed the absolute maximum input voltage of 62V. Ensure the current-limit resistor is properly sized for the desired current; an incorrect value can cause nuisance trips or inadequate protection. The FLT pin is open-drain and requires a pull-up resistor. Verify the startup delay and fault timer settings to avoid unintended shutdowns during inrush.
